Beit known that l, Tllinvnv, Gnnowniinr a citizen of the United States, residing atV Beverl in the count f ofllssex' and State of:

Massachusetts, have invented certain new v,and useful Iniprovementsvin 'lape-lldoisten,` ing Machines; and l do lierebyfdeclarethe.

followin to be a full clear `and exact-:de-

scription of the invention, such as willei'iableA apper-4 -tains to make andiisethesaine.` jf e This invention relates to a tape moisteiiing others skilled in the art to lwhichait machine.

The object of the invention is to reiorV ganize and improve the construction of tape moistening machines to render themA more' eiimicient, practical andbetter adapted to acs. complish thepurposes for which they are de.- Y

` completely cover the -roll of'tape to concealV `it from view and' also' to retainv the pin' 28j in an operative` position and toprevent its with-l signed. Y' a .i Y,

71th this object in view the invention con-V aftei described and claimed.

In the drawings, Figure '1 illustrates. the' y' tap moistening machine .ein Vside -elevations Fig. 2 isy an enlarged detail view showing `the tape severineand holding fdeviceglig. 31is vertical section on theV line 3,-3; ofFig. 2;; and Figs. dand are details tobe referred to. lA tape ymoistening machine embodying the presentqinvention comprises, in generalfaf relatively heavy base portion, a-ino'istening device at one end of the baseportion, a de-i vice mounted on the base fo rotatably sup-l porting a roll of tape, avcover hinged to-thef: rear of the' base capable of c0mpletely-cov-VA lering the roll of tape, and a` device mounted on the base between themoistening-rollfand@ the roll of tape lfor severing the tape when' the free end thereof is manually movedin .anx

upward direction. and for firmly clamping the tape during theosevering operation.

The illustrated embodiment ott-he inven-l tion yisidescribed asA follows: Thetbase 10 is? cast in the form illustrated inl Fig. 1 with; side 4walls 12 Vat, one end portion-ithereof. The side walls 12 are connected by yaftrai'i'sverse wall 5 le' torming a three walled receps tacle in which is kremovably receivedfa trough f 16.; The trough 16 isicormed 'of sheet metal and is' providedwithears 18 extended over;`

l the tops of thelsideriwall-s '12 to retain `the trough in substantial stationaryv position.` within thereceptacle. A moisteiiingroll20, is journaled `in ,open` lV-shaped;groovesv 2.2in

the top of the sides 12 so thatboth the roll 20 andthe-trough 16 may be readily removed.

To these ends i atapefV severingv and clamping {device} is mounteduupon the base 10 ybetween the mois- 85 teningl rol-l2@ and thefroll of tape 26. -The 1 tape severingA and clamping devicefcomprises a A.clamp g' a movable-knife and a toggle connection between the knife and clamp 'whereby i i the strain upontlieknife duringthe sever ing operation is increased by and'ftransmitted through the toggle "connection to the clamp Vsov that the tapeissecurelyheld byth'eclamp comprises, a wire'TO which cooperates with anV elongatedslot 72 in anf abutment Milformed by thefangled upper-'end-jof/ a'bracketpf.

formed byvthefan'gledflowerf end of a second 1i05 y,

bracket 86 riveted tothe upper portion of the .supporting plate 781. The opposite ends'off thegwire 7 Of are extended upwardlyand form connectors 88, theV upper ,out-turned ends of l i. which, extending outwardlyl .through the elongated.. clearance lslots inl the earsj96'nof the-bracket 86, are vpivoted'in holeslinears 90 extended from a knife 92. rlhe knife 92 n ispivoted upona pintle 9.4, the opposite ends of which are carried by the Aears 96 of the bracket 86. The knife 92 and connectors 88 form a toggle, clearly illustrated in Fig. 2,' by which the wire 70 is depressed'when upward strain is placedupon the cutting edge of the knife during the operation of severing the tape. v ,y Y

I The machine is Vprepared for use by siipplying the-trough 1G with water and inserting a roll of tape between theuprights 30,

y. after which the end ofthe tape is passed through the clamp. For this purpose the knife 92 is depressed into the; dotted position illustrated in F ig. l, thereby raising the wire TO away from the abutment 74 so that the end of the tape may be freely passed ythrough i the slot S0 and beneath the wire 70.

In the use of the machine, the "end of the tape is drawn downwardly over `the moistening roll and the drag exerted thereon by the wir@ 70 operates tocausethe tape to hug the moistening roll so as to beefliciently moistened.` j

After the desired length of tape has been inoistened, the free en is moved upward,

thereby drawing the tape against the knife.

j i "The pressure ofthe tape against theknife turns it inits bearings and thereby causes the wire 70`to 'clamp the tape firmlyin a tortuous position between the wire and the sides of the elongated slot, thereby holding itfrom paying off asthe pull upon the tape is continuedfit is severed by the pressure which it exerts upon the knife.

A feature of the invention which'contrib- `utes to the efficient operation of the machine, residesy in the construction of .the clamp, whereby the tape is clamped in a tortuous: position vduring the severingV operation, Yas is shown in detail inFig. 5.

Having thus described the invention what is claimed is l. A tape moistening machine having, in combinatioma base, a roll support mounted thereon, a moistener mounted on the base,

means for severing the tape between 'the Vmoistener and Vroll support, and a clamping device through which the tape passes adapted upon the initiation of the severing operation to depress the tape into a tortuous posii tion and to clamp it in such position during tener at one end of the base, and a tape sev- .ering and clamping device mountedon the the'severing operation. Y y

2.,:A tape moistening machine having, in

combination, a base, means for rotatably supporting a roll oftape on the base, a moisba'se intermediate the moistener and-roll, forV severing the tape and clamping it in a tortu-V ous position by the pressure exerted by the knife during the severing operation.

3. A tape moistening machine having, in

combination, abase, aroll support comprising a pairof uprights `mounted on the base, Y

whereby the tape is clamped in a-tortuous.

position by the pressure exerted upon the knife during vthe severing operation.

4. A tape. moistening machine having, in combination, a base, a roll support, a mois,- tener, a movable knife, a horizontal clamp `beneath which the tapeV passes, an Vabutment provided with a slot therein, a spring for yieldingly holding the clamp and tape against the abutment to frictionally resist its movement thereover, and connections between .the clamp and the knife whereby during the severing operation the clamp is moved'into the slot and cooperates with the sides thereof to clamp' the tapein a tortuous position.k v

5. A tape moistening machine having,'in combination, a base, a rollV support, a moistener, a supporting plate extended vertically;

from the base intermediate the moistener through` which the tape passes from the roll to the moistener, a clamp mounted on the plate and adapted to frictionally resist movement of the tape, aknife pivoted upon' tortuous position between the 'clamp'and-the sides of vthe-"slot duringthe severing operation, and for moving the clamp away from' the abutment to permit the end of the tape to be passed therebetween when the knife is depressed. f Y

7. A tape moistening machine having, in combination,` a base, a rollsupport mounted thereon, a moistener, a knife, aclamp, and a toggle connectionV between theV knife and Vclamp by which the strainV upon the knife during the severing operation is transmitted to the clamp andoperates to clamp the tape securely.

f 8. A tape moistening machine Vhaving,in`

combination, a base, a moistener,` a roll support, aV knife, and a toggle-operated clamp connected r with the knife so .that cuttingv pressure of the tapefonj the knife operates"Y tape is clamped during the severingopera- V and roll support having a slot thereink thefclamp to clamp and-hold the tape from Y paying off during the severing operation.
